WOODS General Engineer, Railway Department, Westinghouse Electric &Manufacturing Company. SAND SPRINGS RAILWAY OIL TANK TRAIN HAULED BY A 50-TON LOCOMOTIVE MANY electric railroads appreciate the possibilityof increasing their revenue by freight trainoperation but do not engage in it because they assumethat increased investment for substation and feedercapacity will be necessary to handle the power properly designed freight locomotive capable of haul-ing a 250-ton train on a 4 per cent grade or a 1500-ton train on the level will produce no higher currentpeaks than a high-speed limited passenger car on thesame line. Freight service is operated by many roadsduring the night. It is well that these off-peak hoursshould be so used instead of permitting the earningpower to drop to zero for four or five hours every fact, freight service need not add a single kilowattto the daylight or evening peaks. It is inherently diffi-cult to obtain a high load factor on most electric rail-roads and the peak load, rather than the continuousload, deter
